Frequently Asked Questions

JSON may store application settings, exports, or structured records. First identify which app created the missing file, then check its export history, backups, and version control. A same-name JSON file from another app may not be equivalent.

Identify the Missing JSON data file (.json)

Confirm the original filename, folder, and storage device. Search for a moved or renamed copy before assuming deletion. If the file still exists but will not open, make a copy and investigate file damage; an undelete scan is not a repair tool.

Avoid starting the application if it would immediately recreate and overwrite the missing file. Preserve any related database or asset folder.

Check Copies and Protect the Drive

Check the Recycle Bin, File History, cloud version history, application backups, and any other device that held the file. If it was cloud-only, use the service's own recovery tools first; a local disk scan cannot search a remote account.

Stop saving to the affected physical drive. New data can overwrite deleted blocks, and SSD TRIM can reduce recovery chances. Set aside a different physical disk for results. If the original device disconnects, makes unusual noises, or reports hardware faults, avoid repeated scans and consider specialist help.

Recover with Qiling Deep Data Recovery

Qiling Deep Data Recovery scans Windows-visible local storage for deleted files. It cannot recreate a file that was never saved, replace missing companion data, or guarantee success after overwriting. Use it only after checking the copies above.

Step 1. Choose the Scan Mode

Open the program. Choose Fast Scan for a recent local deletion, Recycle Bin Scan if the file was emptied from the bin, USB/SD Scan for removable media, or Format Scan if the source was formatted. Match the mode to the event, not just the file extension.

Step 2. Select the Original Location

Select the disk or partition that held the missing JSON data file (.json). Check its drive letter and capacity so you do not scan an unrelated disk. Keep the destination drive separate.

Step 3. Review Candidate Files

When the scan completes, search by original filename and extension if available. Compare folder, date, size, and nearby related files. Keep several plausible versions; a matching name or preview does not establish that the entire file survived. If the first pass finds nothing and the disk is healthy, try the deeper scan option.

Step 4. Save to Another Physical Drive

Select the candidates, click Recover, and save them to the prepared drive. Do not write them back to the source or overwrite a working backup. Test copies rather than the only recovered originals.

Verify Before Reuse

Parse the recovered JSON and compare keys, array lengths, and representative records with an earlier export. Valid syntax alone does not prove completeness.

If one copy is incomplete, compare older backups, exports, and other candidates. Renaming an extension does not reconstruct missing bytes. Once a result is confirmed, back up the file together with any required linked assets or companion files.

Frequently Asked Questions

Can I repair missing JSON by adding a closing brace?

That may make it parse but cannot restore missing records.

Why does a valid JSON file still fail in the app?

It may lack required fields or use the wrong schema version.

Where should I save recovered files?

Use a different physical drive so the recovery output cannot overwrite other deleted data on the source.

Analysis projects can store code and results in formats other than JSON. The following guides distinguish script recovery from serialized objects and scientific data containers: Recover Deleted Python .py scripts on Windows; Recover Deleted Python .pkl files on Windows; Recover Deleted Apache Arrow .feather tables on Windows; Recover Deleted HDF5 .h5 and .hdf5 files on Windows; Recover Deleted MATLAB .mat data files on Windows.
